IMPROVEMENT IN MAKING HAMMERS.

TO ALL WHOM IT MAY CONCERN.:

Be it known that I, J. YERKES, of Fox Chase, in the county of Philadelphia, and State of Pennsylvania, have invented anew and useful Improvement in Hammers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents en inverted pien of' a cast-iron hammer as the same comes from the mould.

Figure 2 is e transverse section of the same.

Figure Sis an inverted plan o f the hammer when ready finished.

Figure 4 is a transverse section of the same.

Similar letters oi' reference indicate like parts.

This invention consists in a cast-iron hammer wit-h claws, which are produced by splitting or sawing 1n such a manner that the edges of said claws are rendered sharp and capable of taking a `firm hold of nails or other articles. Ordinary east-iron hammers are provided with claws which are moulded, but such claws are worthless, because their edges are rounded, and not capable of taking hold of e' nailor other article. The difficulty is avoided by making the hammer according to my invention.

Imould the hammer A with a. deep groove, a, as shown in figs. 1 and 2, and after the same comes from the `sand I open the claws by splitting; or sawing, and thereby the edges of said claws arel rendered sharp, and a. cast-iron hammer is obtained which is cheap, durable, and just as effective as a wrought-iron or steel hammer. In practice my hammers are made of malleable iron, and if desired7 they may be hardened, so as to render them more durable than they are if left in'their natural sof'- state. l

What I claim as new, and desire to secure by Letters Patent, is Constructing clawhammers of Vcast iron in the manner described. y i
